❍RPN MSB/LSB (Controller number 100, 101)

Status	2nd byte	3rd byte
BnH	65H	mmH
BnH	64H	llH
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

mm= upper byte of parameter number specified by RPN ll = lower byte of parameter number specified by RPN

*Not received when Rx.RPN = OFF. (Initial value is ON)

*The value specified by RPN will not be reset even by messages such as Program Change or Reset All Controller.

**RPN**

The RPN (Registered Parameter Number) messages are expanded control changes, and each function of an RPN is described by the MIDI Standard.

To use these messages, you must first use RPN (Controller number 100 and 110, their order does not matter) to specify the parameter to be controlled, and then use Data Entry messages (Controller number 6, 38) to specify the value of the specified parameter. Once an RPN parameter has been specified, all Data Entry messages received on that channel will modify the value of that parameter. To prevent acci- dents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH) when you have finished setting the value of the desired parameter.Refer to Section 5. "Examples of actual MIDI messages" <Example 4> (page 207).

On this unit, RPN can be used to modify the following parameters.

RPN	Data entry
MSB LSB MSB LSB			Explanation
00H 00H	mmH ---		Pitch Bend Sensitivity
			mm: 00H-18H (0-24 semitones),
			Initial Value = 02H (2 semitones)
			ll: ignored (processed as 00H)
			specify up to 2 octaves in semitone steps
00H 01H	mmH llH		Master Fine Tuning
			mm, ll: 00 00H - 40 00H - 7F 7FH (-100 - 0 - +99.99 cents),
			Initial Value = 40 00H (± 0 cent)
			Refer to 5. Supplementary material, "About tuning" (page 208).
00H 02H	mmH ---		Master Coarse Tuning
			mm: 28H-40H-58H (-24 - 0 - +24 semitones),
			Initial Value = 40H (± 0 semitone)
			ll: ignored (processed as 00H)
7FH 7FH	---	---	RPN null
			Set condition where RPN and NRPN are unspecified. The
			data entry messages after set RPN null will be ignored. (No
			Data entry messages are required after RPN null).
			Settings already made will not change.
			mm, ll: ignored

●Program Change

Status	2nd byte
CnH	ppH
n = MIDI channel number		:	0H-FH (ch.1-ch.16)
pp = Program number		:	00H-7FH (prog.1-prog.128)

*Not received when Rx.PROGRAM CHANGE = OFF. (Initial value is ON)

*After a Program Change message is received, the sound will change beginning with the next Note-on. Voices already sounding when the Program Change mes- sage was received will not be affected.

*For Drum Parts, Program Change message will not be received on lower byte of the bank numbers (the value of Control Number 0 is other than 0 (00H)).

●Channel Pressure

Status	2nd byte
DnH	vvH
n = MIDI channel number		:	0H-FH (ch.1-ch.16)
vv = Channel Pressure		:	00H-7FH (0-127)

*Not received when Rx.CH PRESSURE (CAf) = OFF. (Initial value is ON)

*The resulting effect is determined by System Exclusive messages. With the initial settings there will be no effect.

●Pitch Bend Change

Status	2nd byte	3rd byte
EnH	llH	mmH
n = MIDI channel number			:	0H-FH (ch.1-ch.16)
mm, ll = Pitch Bend value			:	00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)

*Not received when Rx.PITCH BEND = OFF. (Initial value is ON)

*The resulting effect is determined by System Exclusive messages. With the initial settings the effect is Pitch Bend.

■Channel Mode Messages

●All Sounds Off (Controller number 120)

Status	2nd byte	3rd byte
BnH	78H	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

*When this message is received, all currently-sounding notes on the corresponding channel will be turned off immediately.

●Reset All Controllers (Controller number 121)

Status	2nd byte	3rd byte
BnH	79H	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

*When this message is received, the following controllers will be set to their reset values.

Controller	Reset value
Pitch Bend Change	± 0 (center)
Polyphonic Key Pressure	0 (off)
Channel Pressure	0 (off)
Modulation	0 (off)
Expression	127 (max)
Hold 1	0 (off)
Portamento	0 (off)
Sostenuto	0 (off)
Soft	0 (off)
RPN	unset; previously set data will not change
NRPN	unset; previously set data will not change

●All Notes Off (Controller number 123)

Status	2nd byte	3rd byte
BnH	7BH	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

*When All Notes Off is received, all notes on the corresponding channel will be turned off. However if Hold 1 or Sostenuto is ON, the sound will be continued until these are turned off.

●OMNI OFF (Controller number 124)

Status	2nd byte	3rd byte
BnH	7CH	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

* The same processing will be carried out as when All Notes Off is received.

●OMNI ON (Controller number 125)

Status	2nd byte	3rd byte
BnH	7DH	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

*The same processing will be carried out as when All Note Off is received.OMNI ON will not be turned on.

●MONO (Controller number 126)

Status	2nd byte	3rd byte
BnH	7EH	mmH
n = MIDI channel number			:	0H-FH (ch.1-ch.16)
mm = mono number			:	00H-10H (0-16)

*The same processing will be carried out as when All Sounds Off and All Notes Off is received, and the corresponding channel will be set to Mode 4 (M = 1) regardless of the value of "mono number."

●POLY (Controller number 127)

Status	2nd byte	3rd byte
BnH	7FH	00H
n = MIDI channel number			: 0H-FH (ch.1-ch.16)

*The same processing will be carried out as when All Sounds Off and All Notes Off is received, and the corresponding channel will be set to Mode 3.
